5. The minimum bending radius of a feeder should be no more than 20 times the
feeder radius, and the bending radius of the main feeder should be more than
0.3m.
6. The indoor and outdoor parts of a feeder should be both above 0.5m. There
should be 0.3m flat and straight at the lightning protection rack.
13.13 Installation and Check of Three-way Feeder Card

the wrapping between a 1/2" jumper and the main feeder connector are as
follows: 1) the connector is wrapped with some waterproof self-adhesive tape; 2)
the waterproof self-adhesive tape at an antenna terminal must be wrapped until
the antenna root; 3) the feeder terminal should be wrapped until 10cm away
from the connector; 4) the waterproof self-adhesive tape is wrapped with an
insulating tape longer than the waterproof self-adhesive tape.
4. At the joint between the jumper and the antennas, they should be parallel to each
other with 30cm in between.
5. The connector is wrapped with a waterproof self-adhesive tape, which must be
extended to an antenna root. Wrap the feeder terminal until 10cm away from the
